Friday Fellow: Northern Plaited Radiolarian

by Piter Boll in Earthling Nature

by Piter Kehoma Boll Some weeks ago I introduced a diatom here and mentioned that, despite the fact that they are a very abundant group, little information on species is available. Today our species is a radiolarian and, just as … Continue reading →... Read more »

Antibiotic cream is NOT 100% effective in preventing Lyme disease

by Microbe Fan in Spirochetes Unwound

A topical antibiotic cream applied to tick bites did not perform any better than placebo in preventing Lyme disease, according to results of a randomized clinical trial conducted in Europe.  The study was published in Lancet Infectious Diseases.I wasn't planning to blog about the study, but I changed my mind after a reader emailed me a link to a news article reporting that the antibiotic cream was 100% effective.  The lead investigator even claimed, "None of the test subjects went on t........

The Lyme disease spirochete lives without thiamine

by Microbe Fan in Spirochetes Unwound

Thiamine, or vitamin B1, is vital for the survival of all living things.  One of the biologically functional forms of thiamine, thiamine pyrophosphate (TPP), is essential for the catalytic activity of several critical metabolic enzymes.  For this reason, we must get thiamine from the food that we eat (or the vitamin pills that we swallow).  Microbes obtain the vitamin from their surroundings, but they can also make their own thiamine if it's not available.It turns out that the Lym........

Bacteria Help Pitcher Plants Trap Prey

by Elizabeth Preston in Inkfish



Pity the insect that tumbles into a pitcher plant's trap. The slippery walls and waiting pool of water ensure it won't clamber back out. There's nothing left to do but wait to be digested.

The California pitcher plant (Darlingtonia californica) is also called the cobra lily for its curled-over shape that hides its exit from its victims. Unlike other pitcher plants, it doesn't fill its trap from above with rainwater but from below, drawing water up with its roots. But like others, it seems... Read more »

Of microbes and men: Evolving as one and terraforming earth

by gdw in FictionalFieldwork

Me and my microbes In the past decade or so, the microbiota, the community of microbes that makes its home in the guts of humans and other animals, has become quite a popular research topic. Quite rightly so, since our little guests seem to affect aspects of our lives that we wouldn’t necessarily consider to […]... Read more »

Responsible resurrection: The ecology of de-extinction

by gdw in FictionalFieldwork

March of the mammoths Improvements in our genetic tinkering capabilities have led several people to suggest potential uses for our newfound powers. Although we ought to add some nuance and note that those powers are still in development. In any case, one of those powers is quite impressive. De-extinction, or the process of bringing back […]...
